The name "nitzechet" does not appear in the Jewish Bible (Tanakh); however, you may be referring to Nitzevet bat Adael, who is known in Jewish tradition as the mother of King David24. Her story is not detailed in the Tanakh itself, but is found in later rabbinic literature, particularly the Talmud and Midrash.

• Nitzevet bat Adael was the wife of Jesse (Yishai), the father of David.
• While the Bible mentions Jesse and his sons, it does not name David's mother. The Talmud and other rabbinic sources identify her as Nitzevet bat Adael4.
• According to tradition, Nitzevet played a significant but quiet role in David's early life. Some Midrashic stories recount that Jesse separated from Nitzevet for religious reasons, and through a twist evocative of earlier biblical stories, David was born amid confusion about his parentage; some believed him illegitimate, but Nitzevet did not reveal the truth to avoid shaming Jesse24.
• Her steadfastness and willingness to endure pain for righteousness are likened to the biblical figure Tamar2.

If "nitzechet" was meant as another Hebrew word or as a reference to a different figure, please clarify your question. If you were thinking of the philosopher Nietzsche or his views on Jews, that is an unrelated topic13.
